Question

the masses of the earth and moon are 6 into 10 raise to 24 kg and 7.4 into 10 raise to 22 kg respectively the distance between them is 3.84 into 10 raise to 5 km calculate the gravitational force of attraction between the two use G= 6.7 × 10 raise to -11 Nm2 kg raise -2

Answer 1

Use formula ...

F = G M1 M2 / r^2

M1 = mass of earth

M2 = mass of moon

r = separation between them

Answer 2

Answer:

20.2 × 10¹⁹ N

Explanation:

Given :

Mass of earth = 6 × 10²⁴ kg

Mass of moon = 7.4 × 10²² kg

Distance between them = 3.84 × 10⁵ km = 3.84  × 10⁸ m

We have value of G = 6.7 × 10⁻¹¹ N m² kg⁻²

We have to find force :

We have :

F = G m₁ m₂ / r²

F = ( 6.7 × 10⁻¹¹ ) ( 6 × 10²⁴ ) ( 7.4 × 10²² ) / (  3.84 × 10⁸ )² N

F = 20.2 × 10¹⁹ N

Hence force exerted by the earth on the moon is 20.2 × 10¹⁹ N.
